To @ZZ whom it' may concern:

Be it known that l, KARL lNnsiin, a suhject of the Emperor of Germany, and a resident of Si Friederikeustrasse, Riittenscheid,

5 near Essen-on-the-Rhr, Germany, have invented certain new and useful Improvements in Impact-Fuses for Exploding Shells, of which the following is a specification.

I This invention relates to that class of imio pact-fuses which by Vvirtue of a device permanentlyincorporated in the construction of the fuse permits the ignition ofthe exploding charge to be so regulated from without the shell or fuse that it takes plaice without or with retardation-that is to say, either immediately on impact of the projectile against the target or after the projectile has penetrated the target.

The invention is especially adapted for the 2o fuse that has been heretofore produced, in which the adjustment to impact or delay action is accomplished by means of a retarding substance permanently introduced in tlie igniting-train, while in 'the channel forming the immediate communication between the percussion-chamber and explosive charge is arranged a cock rotatable from without, this cock being so arranged that it can, according to the purpose desired of the fuse, be fixed,

`through the medium of an arm and tWo rests disposed radially to the turning center of said arm, either in open or closed position, so that when the cock is open the igniting-fiash strikes uninterrupted through the channel into the exploding charge, while in the closed position of the cock the iiash reaches the exf ploding charge onlyafter burning throngh'the retarding substance. f

The present invention has for its purpose to improve the fuse above referred'to in such a manner that the cock will serve the additional function ot' a safety device in transportation. To attain this novel purpose, the cock is capable of being secured in a third position andcarries a cross-piu which when the cock is in said third position intercepts the path ot the movable parts of the fuse.

In thoaccompanying drawings oncembodiment of the invention is illustrated bywav of example.

Figure l is an axial section ot' the fuso in a plane through the axis of the cock and the parte being in impact position, Fig. 2 being a section similar to Fig. l with the parts in transport position, and Figs. 3 and 4 being top 55 views of the fuse in positions corresponding, respectively, to Figs. l and 2.l

In its structural features the present invention corresponds in the main to the previ# ously-known fuse' referred to. rlhe only nia- 6o terial features of difference in the prosentin- ,ready for service.

vention over that referred to are the t'ollowing: A third restjs, in addition to and in'the present illustrative embodiment ofthe invention lying intermediate of the two restsj'j2, 65 is provided,so that the cock-spindle through the medium ot the spring-arm-H can also be secured in the intermediate position. Furthermore, at about the middle ofthe cockspindle V and mounted the'reonis a eross- 7o pin if, presented in the same'direction'as the springearin H, which pin in the turning of the cock-spindle swings in a recess of the fuse-body--R and into and ont of a slotin the deten't-ring B. 75

Vhen the arm H is, as shown in Figs. 2 and 4, in the rest j, (transport position of the fuse,) the cross-pin V fu projects through the slot b of the detent-ring and into'the path of the needle-boltA. In consequence of th'isit 8o prevents both the receding ofthe detent-ring and the advance of the needle-bolt against' the detonating-pellet D. If the fuse is adjusted to impact position by bringing the arm H into the restj,l the ycross-pin o swings ont of the slot b of the'fdetei-'it-ring and out of the path of the needleebolt A, and the fuse is "lhe. saine procedure obtains when the arm H for thepurpose of adjustiny the fuse to delay position is moved from the restj into the restje.

Having thus described the invention, the following is what is claimed as'new therein 1. In a fuse for exploding shells, the oombination of the needle-bolt, apin movable into '95 and ont of the path ol said needle-bolt, a spin dle upon which said pin is' mounted, extending' to the exterior of the fuse, anda lookingarni on the outer end of the spindie, through. n which said pin is adjusted. y los 2. ln a fuse for exploding shells, the coinbination ofthe necdlefbolt, a pin movable 'into to another position to produce a delayed action, and to still another position to hold said movable part against movementso that the fuse may be handled with safety.

4. In a combined impact and-delayaction fuse, having a part thereof movable upon impact to produce ignition, a cock-spindle openlng and closing a passage to produce impact or delay action, and means upon said cockspindle adapted to engage withthe movable part of the fuse when the spindle is in one po` sition, to prevent the movementof'said part so that the fuse may he handled with safety.

5. In combination with a fuse for exploding shells, having a needle-bolt, and a cock-spindle opening and closing a passage to change the effect of the fuse, and a cross-pin carried by said spindle movable into and out of the path of the needle-bolt by the turning of said spindle. A

6.' In combination with a fuse forexploding shells, having a needle-bolt, and a cock-spindle opening and 4closing a passage to change the effect of the fuse, and across-pin carried by said spindle, projecting into the pathof the needle-bolt when vthe cock-spindle is in Y seldorffthis 18th day of an intermediate position but out of said path when the cock-spindle is in either open or'in -one closed position.

V'the needle-bolt when the cock-spindle is in an intermediate position but out of said path when the cock-spindle is in either open or n one closed position, a springarmon the outer end of said cock-spindlethrough which it is moved, and rests securing said armin either of' its positions at will.

8. In a fuse, for exploding shellsthe com# bination of the fusebody, a. needle-holt, a

detent-ring retaining'the needle-bolt, a cock-A spindle turning in said fuse-body, to open and elose'an igni-tiugfchanuel, a cross-pin mounted on said cock-spindle, working through `a recess in the fuse-body and intovand'v out o? a. slot in the detent-ring, andprojeetingiuto the path of the, lleedle-bolt'when the, cockspindle is in its intermediate position', an arm on the outer end of the cock-spindle by which'it is moved, and rests by which said cock-spindle through the arm is secured in open or in closed or in intermediatepositio'n.
